JMT will inventory existing sidewalk, crosswalk, and bus stop locations. JMT will coordinate with the local transit operator and provide existing information regarding transit ridership, stop locations, and frequency of service for the study. In addition, any planned route additions or modifications will be provided to the study team. This data will be used to guide the development of pedestrian, bicycle, and transit recommendations along the arterial roadway network.

Traffic Forecasting

JMT will use existing count data, VDOT historic traffic count data, and RRTPO Regional Travel Demand Model (TDM) to develop traffic growth rates. JMT will use the growth rates and traffic data information available on VDOT Pathways for Planning (P4P) website: https://vdotp4p.com/analyze/traffic-forecast-analysis. The growth rates from P4P will be used to verify the traffic growth projections. The forecasted traffic volumes will be submitted to the SWG for review prior to any analysis being performed. VDOT and Henrico County will provide information related to known potential developments impacting traffic within the study area. JMT will review the TDM to determine if the known developments are captured in the regional model. At the time of this framework document development, VDOT informed JMT that the GreenCity development and planned Magellan Parkway Extension are not included in the 2045 TDM; but during the kickoff meeting RRTPO informed the SWG that the 2050 model is being developed and includes GreenCity development and Part of Magellan Parkway Extension, accordingly, JMT will update the model to include these two developments, if needed. Also, VDOT and the County shared that Scotts Road Bridge over I-95 will be demolished and there is a plan by the County to build a pedestrian bridge in generally the same location.

Safety Review and Analysis

Within the study area, I-95 and Parham Road contain ranked segments of potential for safety improvements (PSI) within the Richmond District based on 2016-2020 and 2017-2021 crash databases. Additionally, Parham Road contains PSI intersections. The PSI list identifies segments or intersections that have experienced more crashes than what is predicted for that site based on safety performance functions and ranks those sites based on that differential. Note that PSI ranks for segments and intersections were obtained from the 2016-2020 and the 2017-2021 PSI databases, since the latter only includes VDOT maintained segments and intersections. The PSI locations will serve to help prioritize where to focus safety improvements because they have the highest potential to improve safety; however, a detailed safety analysis will be conducted within the entire study area using five-year historical crash data, downloaded from VDOT’s PowerBI crash database, to compare to the PSI rankings and identify hot spots, contributing factors, and countermeasures to address and prioritize safety needs. The historical intersection crash analysis results will be compared with the PSI ranked intersections as the PSI rank indicates a higher prioritization. Figure 3 and Figure 4 summarize the PSI segments within the study area which include the following segment and intersections:

• Parham Road at Route 1 (Rank 26) – Source 2017-2021 database

VDOT Pedestrian Safety Action Plan (PSAP) segments within the study area are shown in Figure 5 and Figure 6, Source: Pedestrian Safety Action Plan (PSAP) 3.0 database and include:

• East Parham Road from Best Plaza Drive to East of Magellan Parkway (District Top 5% Corridors)

JMT will conduct a review of the most recent five years of available crash data, assumed to be 2018-2022. The crash review will include the development of intersection crash summaries and the identification of crash patterns. JMT will review pedestrian crashes to determine what proportion of crashes are related to pedestrians and bicyclists along Parham Road. Density heat maps along I-95 will also be created to visualize the crash patterns within the study area.
